Abstract: This paper provides the effect of magnetizing inrush current on the power transformer. At the time of energization power transformer draws high current called transformer inrush current. With the help of Triac, as a high switching device magnitude of inrush current at various switching angle is studied. Inrush current normally appears due to saturation of magnetization of the iron core, when power transformer is switched on no load. In the proposed method Triac is used for the short period of time for energization of the transformer. By controlling the phase angle of Triac magnetic inrush current is reduced. To study the performance of proposed method simulation of power system model is carried out in MATLAB and inrush current at various switching angle is studied
